' FAN ATTACHM ENT'FOR BICYCLES.

SPECIFICATION forming part of Letters Patent N 0. 702,003, dated June10, 1902.

Application filed May 18,1901.

To all whom it may concern:

Be itknown that I, PHILIP EDWARD HAN- NUM, a citizen of the UnitedStates, residing at Carthage, in the county of Jasper and StateofMissouri, have invented a newand useful Fan Attachment for Bicycles, ofwhich the following is a specification.

This invention relates to fan attachments for bicycles, and has for itsobject to provide a novel form of combined fan and canopy adapted to beoperated by the current of air produced by the movement of the bicycleand to direct such current in part downward upon the rider.

With this and otherobjects in view the present invention consists in thecombination and arrangement of parts, as will be hereinafter more fullydescribed, shown in the accompanying drawings, and particularly pointedout in the appended claims, it being under stood that changes in theform, proportion, size, and'minor details may be made within the scopeof the claims without departing from the spirit or sacrificing any oftheadvantages of the invention.

In the drawings, Figure 1' is a side elevation of a portion of the frameof a bicycle having the present device applied thereto, parts beingbroken away to show the adjustable connectionsthereof. Fig. 2 is'anenlarged detail sectional view to show the rotatable support for thecanopy. Fig. 3 is a'plan section taken on the line 3 3 of Fig. 2. I

Like charactersof reference designate cor-. responding parts in allofthe figures of the drawings. I

In carrying out the present invention there is provided a substantiallytriangular supporting-bracketl, the front side of which is vertical andthe rear side of which is inclined upwardly and rearwardly and alsoprovided with a longitudinal groove forming a seat for the reception ofthe front side of the headtube 2 of any ordinary bicycle-frame, therebeing suitable clamps 3 carried by the bracket and constructed toembrace the head-tube, so as to rigidly connect the bracket thereto. Inthe top ofthe bracket there is provided a socket for the reception of atubular standard 4, rising rigidly from the bracket and extending to asuitable height above the handlebars of the bicycle. Within the upperend Serial No. 60,912. (No model.)

of this tubular standard there is telescopically mounted anextension-rod 5, which may be held at any adjustment by means of asetscrew or clamp 6, piercing the upper portion of the tubnlar'standardand-designed to engage the rod. At the upper end of the rod there isprovided a tubular elbow'7, which is fixed to the rod and is projectedrearwardly therefrom, the horizontal arm thereof being extended for theadjustable reception of a rod' 8 and having aset-screw 9 for theadjustment of the rod.

At the rear and outer end of the horizontal rodS there is provided afixed substantially horizontal bracket '10 (best shown in Fig. 2) andpreferably in the form of a flat circular plate having a central opening11 and a con centric groove 12, formed in the upper face thereof and forthe reception of a plurality of antifriction-balls 13. Upon the top ofthis fiat bracket there is provided a circular rotatable head 14,supported upon the antifriction-balls and provided with a centralopening 15, corresponding to that of the bracket, I there also beingopposite notches 16, formed in the top of the head and intersecting thecentral opening. A plurality of upstanding hooked or shoulderedprojections 17 rise from the marginal edge of the bracket, so that theupper terminal shoulders or lips 18 may overhang the marginal edge ofthe rotatable head, thereby preventing lateral displacement of thelatter and permitting ofthe same rotating upon the bracket.

p The canopy is preferably in the form of an ordinary umbrella 19,having the usual stick 20, which is designed to be received throughthe'correspondin g central openings in the ro- For connecttatetherewith, there is provided a socket consisting of oppositesubstantially semitubular members 21, which are designed to embrace thestick and are clamped thereon by means of elastic bands or clamps 22,that normally lie between pairs of lateral projections 23, formedintegrally with the respective socket-sections, whereby displacement ofthe clamps is prevented. This socket is first inserted through theopenings in the head and bracket, the members thereof being in mu.- tualcontact, so as to pass the lower projec= IUD tions through the openings,after which the umbrella-stick or canopy-standard is thrust into theupper end of the socket, which frictionally grips the stick, so as to beconnected therewith. The intermediate portion of each socket-section isprovided with a lateral projection 24, which is of a size to fit snuglywithin the corresponding notch in the top of the rotatable head, therebyto interlock the socket and the head against independent r0- tation,there being a pivotal finger or latch 25 mounted upon the head andadjacent to each notch, so as to be swung across the same and theprojection therein to prevent upward displacement of the socket from thehead.

To provide for rotating the circular canopy, a plurality of radial andlaterally-inclined blades 26 are arranged upon the top of the canopy, sothat when the bicycle is in motion the current of air generated therebywill act upon the blades to rotate the canopy. Upon the under side ofthe canopy there are provided a plurality of radial fan-blades 27,whereby the rotation of the canopy will carry the fan-blades therewithand direct a current of air downwardly toward the bicycle-saddle and forthe comfort of the rider. In order that the speed of the fan may beregulated, there is provided a brake device consisting of a set-screw28, piercing the rotatable head, with its inner end in frictionalrelation to the upper face of the bracket 11, so as to retard the motionof the head when the screw is in engagement with the bracket.

What is claimed is- 1. A bicycle attachment comprising a support adaptedfor application to the frame of a bicycle, and a bladed fan-carryingcanopy revolubly mounted upon the support.

2. A bicycle attachment comprising a rovoluble canopy or sunshadeprovided on its upper side with blades and on its under side with afan.

3. A bicycle attachment comprising a support adapted for application toa bicycleframe, a rotatable socket mounted upon the support, and abladed fan-carrying canopy having a standard detachably mounted in androtatable with the socket.

4. A bicycle attachment comprising a support, adapted for application tothe frame of a bicycle, and provided with a vertically-disposed opening,a rotatable head having a central opening corresponding to thefirstnamed opening, and provided in its outer face with recessesintersecting the opening, a socket fitted in the corresponding openingsand provided with lateral projections to engage the respective recessesto interlock the socket with the head, and a bladed fancarrying canopyhaving a standard detachably mounted in the socket and rotatabletherewith.

5. A bicycle attachment having a circular bracket provided with acentral circular opening, a circular rotatable head mounted upon thebracket and provided with a central opening corresponding to that in thebracket, and with recesses intersecting the opening, a plurality ofupstanding marginal guards rising from the bracket and embracing themargin of the head, a socket fitted through the corresponding openingsand provided with lateral projections fitting in the recesses, pivotedlatches upon the head 'and constructed to lie across the recesses andthe projections, a standard removably fitted in the socket and rotatabletherewith, and a bladed fan-carrying canopy mounted on the standard.

A bicycle attachment having a support provided with a vertical openingand a concentric groove in its upper face, antifrictionballs movable inthe groove, a rotatable head mounted upon the balls and provided with acentral opening registering with that of the support, a standardremovably fitted in the said openings and connected with the head, and abladed fan-carrying canopy mounted on the standard.

7. A bicycle attachment having a support provided with verticalopenings, a sectional socket rotatably mounted in the openings,one ormore elastic bands embracing the sections of the socket, and a bladedfan-carrying canopy having a standard clamped within the socket.

8. A bicycle attachment having a support, a rotatable head mountedthereon, a bladed fan-carrying canopy supported upon the head, and aset-screw piercing the head and frictionally engaging the support.

In testimony that I claim the foregoing as my own I have hereto alfixedmysignature in the presence of two witnesses.

PHILIP EDWARD IIANNUM.
